I use an immersion heating rod in a bucket to heat the water. The process takes around 10-15 minutes. I wish to heat another bucket full of water simultaneously when the water in the first bucket is getting heated-up. My purpose is to use a single immersion rod and heat two buckets at once. The process will definitely take double time but it is fine with me. Is there any way that I can use some coils or metal rods that if placed in the two buckets could transfer heat from one bucket and heat the water in another bucket also? Please suggest any other ways, approaches or materials to use. Thanks.
Assuming that you want to do both buckets at once because you wish to avoid having to swap the heating rod between the two buckets:
The simplest way is to use a larger container that can hold at least as much water as both of the smaller buckets combined. That way, the water itself will serve the purpose of circulating the heat, and your two smaller buckets are at the ready for whenever you need them. If the larger bucket has a spout at the bottom (or some other simple way of getting the heated water out), then you can keep both smaller buckets at the ready and fill them when you need them.
Two buckets, two siphons full of water, one situated at the top of each bucket, and one situated on the bottom of each bucket insulated. put the heater in one of the buckets. As water is heated, it rises to both buckets because of the upper siphon that is full of water, and is replaced by colder water from both buckets because of the siphon connection at the bottom of both buckets, thereby heating both buckets at the same time, no connections, no leaks. Be sure to place the heater away from the siphon so that no bubbles get in the hose and break the siphon.
It might work just under very specific conditions, but here it goes:
- you will need two buckets, one smaller than the other, and the smaller one has to be made of a conducting material (any non-painted metal would do, I guess).
- Put the smaller bucket inside the bigger one, and fill both with water. The smaller one will be filled like always, but the bigger one will be filled just in the sides, as it will contain the smaller one inside.
- Put the immersion rod in the smaller bucket, and turn it on.
- Once the water inside the smaller bucket is heated, it will start heating the water in the bigger bucket, as heat will be conducted through the metal.
Some heat might get lost during the procedure, mostly due to the metal used I guess.
Obviously You want two buckets to get hot At once due to simultaneous usage of hot water during the same period of time. The Best method would be To fill Both buckets and leave the rod in one of the buckets. Once it heats up and is ready for usage quickly just change the rod to hang in the other bucket and use the hot water whilst the other person waits. Or If you really are desperate buying a second rod is a must. It would cost you a little more money but would make life a whole lot easier. Unfortunately connecting metal wiring and trying to get the rod connected to another bucket is too risky and you may get electricuted. Do not try Funny stuff when handling water and electricity.
I will assume you have two Home Depot style buckets of the same size that need to be heated at the same time and for the sake of not having to monitor, you want them to simultaneously heat until both are at about a heated equilibrium. Efficiency is also not a factor.
The hard way: I seem to recall this exercise that should when scaled fit your purpose..if I recall it correctly.
You will need a 6-12" platform, a two fuel siphon hoses or equivalent garden hoses, clamps, and a weight of some sort in addition to your immersion rod and buckets.
Place the immersion rod in the lower bucket. Then place the first hose a couple (1-2") under water inches of each bucket. Then place the second hose laying sideways or 1" from the bottom of both buckets. Important for this to work when placing those hoses initially you have to have vacuum (water filled with pressure) in each hose.
The Easy Way: Alternately you if want guaranteed circulation, I would just get electric utility pump, depending on purpose use of water a submersible utility / sump pump, or one they sell to fit directly on top of the Home Depot style buckets, not if two pumps they need to have the same flow rate. They also sell ones specifically for recirculating/mixing ( 2x in / 2x out) so you don't need two pumps just one. This would allow you to for go / skip the elevation, maintaining vacuum, and whole physics hassle.
- Place the two buckets next to each other.
- Take a length of copper wire, wrap this around the heating element several times. Remove the coil you've made from the heating element.
- Wrap the other end of the copper wire around the heating element several times. Keep enough space between the two coils that you can dip one coil (on the heating element) in one bucket, and the other coil in the second bucket.
- Repeat step 2 and 3 several times, so you end up with several coils of wire on the heating element, and several wires going from one bucket to the other. The more the better (increased heat transfer).
Of course, all proposed solutions ignore that it's much easier to heat one bucket, then the other. You spend far more time jury-rigging the buckets than you save by heating them at the same time. And if you're going to buy copper wire, it's probably cheaper to buy a 20-litre bucket instead.
